I checked for any signs of rubbing and didn't see any. Chain is in great shape. Looks like I have about 3/4 of an inch in chain slack measured vertically so I assume that's ok? And that was done by eyeball method. I probably need to calibrate them a little. But it does not seem overly loose or tight.
So that means I may be looking at something internal. For just taking a peek inside, is it involved in a lot of items to be removed?
